UTL Form 4: Anne Alonzo vested 2,435 RSUs, post-transaction 4,017 shares owned

Rhea-AI Filing Summary

Anne L. Alonzo, a director of Unitil Corporation (UTL), reported transactions on 10/01/2025 showing the vesting and settlement of restricted stock units and an associated sale. She was granted 2,435 restricted stock units that are fully vested on grant and payable 70% in common stock and 30% in cash based on the closing price the day before settlement. The filing reports a disposition of 1,276 shares of common stock (code V), and shows 4,017 shares of common stock beneficially owned following the reported transactions. The form is signed by an attorney-in-fact and dated 10/03/2025.

The disclosure is a routine Section 16 Form 4 reporting compensation-related equity (restricted stock units) that vested and the resulting share sale, rather than a corporate event or financial restatement. All figures and mechanics reported here are limited to the grant, its settlement mix (stock/cash), the number of shares sold, and the resulting beneficial ownership.

Positive

• 2,435 restricted stock units are fully vested, aligning director compensation with shareholder value
• RSUs pay 70% in stock and 30% in cash, providing mixed liquidity and equity alignment

Negative

• Disposition of 1,276 shares (code V) reduces insider ownership and may be viewed as insider selling
• Post-transaction direct beneficial ownership is only 4,017 shares, a modest holding level
